局域网内PGIS地图的使用
局域网PGIS地图的使用：以天地图做打底，使用leaflet.js交互式地图 JavaScript 库做开发。

轨迹：https://blog.51cto.com/BADAOLIUMANGQZ/6843897
PS：相关搜索可搜Leaflet.MovingMarker-master
主要功能包括点的标记，区域的展示，以及点的点击事件；点的添加展示，区域的绘制，回显，编辑，删除；热力图；PGIS轨迹回放功能。相关代码如下：
一、点的标记，区域的展示，以及点的点击事件
相关代码组件如下，此组件整合了热力图的展示，具体根据实际业务需要选择性展示：

三、热力图的关键代码
在index.html页面引入js
<!-- 热力图 -->
<script type="text/javascript" src="HeatmapOverlay.js"></script>
热力图相关主要代码：
//热力图 initHotMap(){ var that = this //热力图添加之前先把之前的热力图层去掉，以防止多次重复添加 let all = this.map._layers let arr = Object.values(all) arr.map(item=>{ if (item.class === "heatA") { that.map.removeLayer(item); } }) let heatDataList = [ // { lat: 39.6408, lng: 116.7728, count: 1 }, // { lat: 39.75, lng: 116.55, count: 1 }, // { lat: 39.55, lng: 116.55, count: 100 }, // { lat: 39.65, lng: 116.45, count: 1 }, // { lat: 39.45, lng: 116.35, count: 1 }, // { lat: 39.35, lng: 116.25, count: 1 }, // { lat: 39.25, lng: 116.15, count: 1 } ] // 构造热力图数据 this.houtData.forEach((v) => { // 纬度、经度、阈值 var aa = v.coor let group = [aa[0], aa[1], v.count] heatDataList.push(group) }) // 生成热力图图层，并添加到地图中 let heat = L.heatLayer(heatDataList, { radius: 12, minOpacity: 0.2, gradient: { // 自定义渐变颜色，区间为 0~1 之间(也可以不指定颜色，使用默认颜色) '0.25': 'rgba(0, 0, 255, 1)', '0.55': 'rgba(0, 255, 0, 1)', '0.85': 'rgba(255, 255, 0, 1)', '1': 'rgba(255, 0, 0, 1)' } }); heat.class='heatA' heat.addTo(this.map) },
四、PGIS局域网地图的轨迹回放
